chore(media): retire the legacy Jellyfin block from dankserver/compose.yaml

The container has had one owner since the Quadlet cutover
(dankserver/jellyfin/quadlet/jellyfin.container). The block was a second owner,
and wrong on every path: jellyfin/jellyfin:latest instead of the pinned ghcr
image, /opt/jellyfin/* data roots that no longer exist, and a read-only
/mnt/entropy:/data bind that the metadata view has since replaced.

The planner no longer counts jellyfin as a compose service, so editing the
inventory cannot restart a media server; tests/deployment_scoping.bats pins that
contract for both jellyfin and plex.

+# Media Metadata View
+
+`/var/lib/media-meta/view` is an OverlayFS merge of the media library: the RAID6
+array below, a directory on the NVMe above. It exists so [[Jellyfin]] can write
+Kodi-format sidecars (`movie.nfo`, `tvshow.nfo`, `episode.nfo`, artwork) that
+[[Plex]] can read. Sidecar metadata is only useful sitting next to the media
+file, and the array is read-only and slow — so the media bytes stay there and the
+*writes* land on SSD. One tree to both servers, one copy of the media.
+
+The mount point is not a volume and holds nothing while unmounted. It sits inside
+`/var/lib/media-meta` so that layers, kernel bookkeeping, the reap trash and the
+merged door are one directory — and so the mount table grows no new `/mnt` entry
+next to the array.
+
+## Shape
+
+| Item | Value |
+|---|---|
+| Lower layer | `/mnt/entropy` — the RAID6 array, source of truth, never written |
+| Upper layer | `/var/lib/media-meta/upper` — NVMe; every write lands here |
+| Work dir | `/var/lib/media-meta/work` — overlayfs internals, same filesystem |
+| Mount point | `/var/lib/media-meta/view` — the merged tree both servers bind |
+| Unit (repo) | `dankserver/host/systemd/media-meta-view.mount` — the source of truth |
+| Unit (host) | `var-lib-media\x2dmeta-view.mount` — systemd names a mount unit after its escaped path (`-` becomes `\x2d`); `media-view.sh install` writes the repo file under that name |
+| Installer | `scripts/media-view.sh` — `plan` / `install` / `verify` / `status` / `reap` |
+| Written by | Jellyfin only (Plex binds read-only); nothing else in the fleet touches it |
+
+Both consumers guard the view with
+`UnitConfigItem=ConditionPathIsMountPoint=/var/lib/media-meta/view`, and
+`scripts/deploy.sh dankserver --service jellyfin|plex` calls `media-view.sh
+install` + `verify` before it restarts either container.
+
+| Consumer | Bind | Mode | Why that path |
+|---|---|---|---|
+| [[Jellyfin]] | `/var/lib/media-meta/view:/data` | rw | It is the metadata writer; its sidecars become SSD bytes |
+| [[Plex]] | `/var/lib/media-meta/view:/mnt/entropy` | ro | Every path in the PMS database was recorded as `/mnt/entropy/...`; only the HOST side of the bind moved, so its database still resolves |
+
+Putting the sidecars inside Plex's reach is not the same as making Plex use them:
+a library parses `.nfo` only with its *Local media information* agent enabled, and
+this change touches no library setting.
+
+## Commands
+
+```bash
+scripts/media-view.sh plan              # print the resolved shape, touch nothing
+sudo scripts/media-view.sh install      # create dirs, install the unit, mount, enable
+scripts/media-view.sh verify            # is the view really the overlay? (deploy gate)
+scripts/media-view.sh status            # mount options + upper-layer size/file count
+scripts/media-view.sh reap              # list ghost metadata (media moved, sidecars left)
+sudo scripts/media-view.sh reap --apply # move ghosts to the SSD trash, never delete
+```
+
+`--upper-base DIR` and `--lower DIR` relocate the layers for `plan` and `reap`;
+the defaults are the host values above.
+
+## Laws
+
+- **The upper layer must sit on non-rotational storage.** `install` and `verify`
+  refuse via `lsblk -dno ROTA` if the upper base lives on the array: an overlay
+  whose upper is the spinners is the original problem with extra steps, and it
+  silently turns every metadata write back into a seek.
+- **Never mount the view over an unmounted lower.** `RequiresMountsFor=/mnt/entropy`
+  plus the container `ConditionPathIsMountPoint` guards: an empty `lowerdir`
+  presents an *empty library* as truth, and a media scan would then clear the
+  database of everything. systemd does not create a mount point, so `install`
+  creates `view` itself; without it the mount simply fails.
+- **Never delete through the view.** A delete writes an overlayfs whiteout
+  (`.wh.<name>`) in the upper layer, which hides the array's copy without
+  removing it — the file reappears the moment the view is unmounted, and the
+  upper layer now carries a landmine. Deletions belong on the raw path
+  (`/mnt/entropy`), which the relayout tool already treats as the only writer.
+  `reap` refuses to remove whiteouts and only warns about them.
+- **A relayout must be followed by `reap`.** Renames happen on the raw path, so
+  sidecars the view already wrote stay at the old coordinates: a ghost folder
+  the servers browse and find nothing in. `reap` lists upper-layer directories
+  with no counterpart below and moves them (with their subtree) into a dated
+  `.AGENTTRASH/` under the SSD base. It is recursive and file-safe: a sidecar
+  that exists only above is normal, so only *directories* are candidates.
+- **File-watcher events do not cross the overlay.** Plex's NFO agent and
+  Jellyfin's real-time monitor see inotify events for writes that land *in the
+  upper layer*, not for changes on the array underneath. After any relayout or
+  externally-written metadata, trigger a library refresh — see
+  [[Media Relayout]] for the refresh procedure.
+
+## Failure signatures
+
+| Symptom | Meaning |
+|---|---|
+| `jellyfin.service` / `plex.service` show `ConditionPathIsMountPoint=... was not met` and stay inactive | The view is not mounted. Do not start them anyway: `scripts/media-view.sh install`, then `verify`. |
+| Jellyfin log: `Read-only file system : '/data/Movies/…/movie.nfo'` | The container is binding the raw array, not the view — the quadlet drifted back or the view is gone. `media-view.sh status`. |
+| A folder appears in a media server with artwork/`.nfo` but no video | Ghost metadata from a relayout. `media-view.sh reap`. |
+| `verify` prints `refused: …/view is not a mountpoint` | A plain directory is sitting where the overlay belongs. That is the fail-closed guard working; `install` on the box. |
+| `systemctl status` finds no such unit | Look under the escaped name, `var-lib-media\x2dmeta-view.mount`, not the repo file name. |
+
+## Rollback
+
+Revert the commit that pointed the two quadlets at the view and re-deploy both
+services — they bind `/mnt/entropy` read-only again, which is the pre-view shape.
+The NVMe upper layer can stay: nothing reads it once the binds are back, and it
+holds no state either server needs. Unmounting alone
+(`systemctl stop 'var-lib-media\x2dmeta-view.mount'`) is safe while no container
+binds it, and the array is never modified by any of this.
+

+# Seam: the SSD-backed metadata view (OverlayFS) that lets Jellyfin write
+# Kodi-format sidecars for Plex to read, without ever writing to the spindle
+# array and without letting either media server start against a missing view.
+#
+# The contracts, in the order the seam tests them:
+#   1. the plan puts the writable layer on the SSD and the media layer below it;
+#   2. bad input is refused by name instead of mounting something surprising;
+#   3. verify refuses a view that is not mounted (so nothing trusts a directory);
+#   4. both media units bind the VIEW and refuse to start without it;
+#   5. only those two units touch the view — the LLM and library tenants keep the
+#      raw volume, so the blast radius is two containers;
+#   6. the deployer brings the view up BEFORE it restarts either server;
+#   7. the planner routes a change to these files to both media services.
